Elevated serum levels of Interleukin‐37 are associated with inflammatory cytokines and disease activity in rheumatoid arthritis

Interleukin‐37 (IL‐37) is closely associated with several inflammatory diseases. However, the role of IL‐37 in the pathogenesis of rheumatoid arthritis (RA) remains unclear. The aim of this study was to assess the associations between serum levels of IL‐37 and disease activity, inflammatory cytokines, and bone loss in patients with RA. Serum cytokines levels were examined by Enzyme‐linked immunosorbent assay (ELISA). Radiographic bone erosion was assessed using the van der Heijde‐modified Sharp score and bone mineral density (BMD) was measured using DXA. Serum IL‐37 levels in RA patients were significantly higher than those in HCs (p < 0.001), and were significantly positively correlated with clinical parameters of disease activity and serum levels of IL‐17 and IL‐23. In addition, serum IL‐37 levels were significantly higher in patients with stage IV of radiographic bone erosion than those with stage III and stage I–II, and they were significantly higher in those with osteopenia and osteoporosis than in those with normal BMD. Our results suggest that serum IL‐37 levels were increased in patients with RA and were positively associated with disease activity, IL‐17/IL‐23 and bone loss in RA, suggesting that IL‐37 may play a critical role in the pathogenesis of RA.     

血清谷丙转氨酶水平与不同性别2型糖尿病患病的关系

目的 探讨血清谷丙转氨酶（ALT）与新诊2型糖尿病（T2DM）患病风险之间的关联，为T2DM的防治提供科学依据。方法 采用4阶段分层随机抽样的方法选取2006年和2009年参与青岛糖尿病预防项目的研究对象男性3 012例、女性4 422例，采用Pearson相关检验分析不同性别ALT与FPG、2 h PG的相关性，并利用多因素logistic回归分析ALT与新诊T2DM患病的关系。结果 男性中，ALT与空腹血浆血糖（FPG）、餐后2 h血浆血糖（2 h PG）的Pearson相关系数分别为0.088、0.080（均P＜0.01）；多因素logistic回归显示，在调整了年龄、BMI、糖尿病家族史、城乡、教育、婚姻、收入、吸烟及饮酒状况等混杂因素后，ALT的第4分位（Q4）组新诊T2DM患病风险是第1分位（Q1）组的1.832倍（OR = 1.832，95% CI:1.324～2.534，P＜0.01）。女性中，ALT与FPG、2h PG的Pearson相关系数分别为0.065、0.108（均P＜0.01）；多因素logistic回归显示，在调整了年龄、BMI、糖尿病家族史、城乡、教育、婚姻、收入、吸烟及饮酒状况等混杂因素后，ALT的第4分位（Q4）组新诊T2DM患病风险是第1分位（Q1）组的1.445倍（OR = 1.445，95% CI:1.087～1.919，P＜0.05）。结论 在男、女性人群中，ALT水平升高与T2DM患病相关，且这种相关性不受年龄、BMI、糖尿病家族史等的影响。     

Hair shaft miRNA‐221 levels as a new tumor marker of malignant melanoma

miRNA‐221 (miR‐221) is known to be abnormally expressed in many human cancers. The serum levels of miR‐221 have been reported as a tumor marker for malignant melanoma (MM). We hypothesized that the hair shaft miR‐221 levels may be increased in patients with MM. We therefore assessed the possibility that hair shaft miR‐221 levels could be a marker for MM. The hair shaft miR‐221 levels were significantly higher in patients with MM than controls. The rates of increased hair shaft miR‐221 levels above the cut‐off value were comparable to those of serum 5‐S‐CD, which is a tumor marker commonly used for MM. Measurements of the hair shaft miR‐221 levels could have potential clinical value in the detection of MM. This is the first report investigating the hair shaft levels of an miRNA in patients with MM. Our investigations offer new insight into the relationship between miR‐221 and MM, and may provide a new, non‐invasive way to screen for melanoma.

Cancer/health communication and breast/cervical cancer screening among Asian Americans and five Asian ethnic groups

ABSTRACT

Objectives: This paper is an examination of cancer/health communication factors (i.e. cancer/health information seeking, patient-provider communication (PPC), cancer screening information from providers) and screening for breast and cervical cancer among Asian Americans and five Asian ethnic groups (Chinese, Filipinos, Japanese, Koreans, Vietnamese) in comparison to Whites. Additionally, the relationship between cancer/health communication disparity and cancer screening gaps between Asian Americans and Whites was investigated.

Design: Data comes from a nationally representative sample of 2011–2014 Health Information National Trends Surveys (HINTS).

Results: Asian Americans and most Asian ethnic-groups reported significantly lower rates of cancer/health information seeking and lower evaluations for PPC as compared to Whites, though differences within Asian ethnic groups were observed (Koreans’ greater cancer/health information seeking, Japanese’ higher PPC evaluation). When the cancer/health communication factors were controlled, Asian Americans’ odds of cancer screening were increased. Especially, Asian Americans’ odds of adhering to the breast cancer screening guideline became nearly 1.4 times greater than Whites.

Conclusion: This research demonstrates that health organizations, providers, and Asian American patients’ collaborative efforts to increase the access to quality cancer information, to make culturally competent but straightforward screening recommendations, and to practice effective communication in medical encounters will contribute to diminishing cancer disparities among Asian Americans.

肺腺癌对一代EGFR-TKIs原发耐药的危险因素分析

目的:分析对一代表皮生长因子受体酪氨酸激酶抑制剂(epidermal growth factor receptor-tyrosine kinase inhibitors,EGFR-TKIs)原发耐药的EGFR突变肺腺癌患者的临床特征,为预测肺腺癌患者是否对一代EGFR-TKIs原发耐药提供依据。方法:收集2014年01月至2019年04月于本院住院,一线使用一代EGFR-TKIs且随访时间超过6个月的EGFR敏感突变(19Del/21L858R)肺腺癌患者,根据疗效纳入原发性耐药组(NR=40)和敏感组(NS=237),比较两组患者的临床、影像特征及实验室指标之间的差异,分析对一代EGFR-TKIs原发耐药的危险因素。结果:EGFR敏感突变患者的原发性耐药发生率为14.4%。原发性耐药组与敏感组患者相比,二者在吸烟指数(P=0.004)及淋巴结转移(P=0.03)的差异有统计学意义。血清神经元特异性烯醇化酶(neuron specific enolase,NSE)≥10.725 ng/mL、肿瘤直径≥3.55 cm的患者更易对一代EGFR-TKIs耐药(P<0.05),各因素AUC值分别为0.615、0.716。联合NSE+肿瘤直径两项指标时AUC为0.735(95%CI:0.665~0.804),联合NSE+肿瘤直径+吸烟指数三项指标时AUC为0.751(95%CI:0.679~0.822),均优于单项指标。多因素Logistics回归分析证实,血清NSE浓度、肿瘤直径及吸烟指数是预测EGFR敏感突变患者对一代EGFR-TKI原发耐药的独立影响因素(P<0.05)。结论:吸烟指数≥400、病灶直径≥3.55 cm、血清NSE浓度≥10.725 ng/mL的患者更易对一代EGFR-TKIs原发耐药。单因素对预测EGFR突变患者是否对一代EGFR-TKIs原发耐药准确性较低,综合上述三项指标预测效果更好。
